One of the risks of playing public if you ask me. You should enjoy the chaos. If you wanna co-op with control then invite people you want on it instead.

...this wasn't on a public server but one my friend setup.

Tbh im surprised they havent got a option that allows you too stop people coming in from other servers

You're free to make your own world, where you can kick and ban people for playing the game in a way you don't like.
